items never expire? about bigcache

[shiftregister-vg]

@unisqu I missed it too, you need to also set CleanWindow in your config.

Here's a config that I'm using that does expire items after 30 minutes

cacheConfig := bigcache.Config {
    Shards: 1024,
    LifeWindow: 30 * time.Minute,
    CleanWindow: 30 * time.Minute,
    MaxEntriesInWindow: 1000 * 30 * 60,
    MaxEntrySize: 500,
    Verbose: true,
    HardMaxCacheSize: 1024,
    OnRemove: nil,
    Logger: cacheLog,
}

Hi, can you show your code? It's hard to guess what you're doing 😉

Closing as resolved. :)

im getting this error too, I have set a clean window to 1hr, and a lifetime of 12hr, but content is not getting cleaned.

Code:

// NewCache is used to instantiate our bigcache content cache
func NewCache(opts config.Cache) (*Cache, error) {
	// parse content life time into time.Duration
	lifetime, err := time.ParseDuration(opts.Content.LifeTime)
	if err != nil {
		return nil, err
	}
	// parse cache clean window into time.Duration
	cleanwindow, err := time.ParseDuration(opts.Content.CleanWindow)
	if err != nil {
		return nil, err
	}
	// generate a default bigcache config
	cfg := bigcache.DefaultConfig(lifetime)
	// set the maximum size of the cache in megabytes
	cfg.HardMaxCacheSize = opts.Content.MaxSizeInMB
	// set how often we should attempt to clean the cache
	cfg.CleanWindow = cleanwindow
	// instantiate our bigcache
	bc, err := bigcache.NewBigCache(cfg)
	if err != nil {
		return nil, err
	}
	// return the content cache
	return &Cache{
		bc,
	}, nil
}
